Abstract
Official abstract text for this publication.
An intersecting-axes gear type mechanism includes two gears configured to rotate in mesh with each other. Respective axes of rotation of the two gears being disposed in an intersecting-axes manner, and at least one of the gears has teeth each of which includes a tooth trace extending substantially in a radial direction and a radially inner end face. A chamfered portion is formed on a meeting portion where the radially inner end face and a tooth face of the each of the teeth meet, so as to extend over an overall length of the meeting portion. At least an entirety of an area where the chamfered portion and the radially inner end face meet and an entirety of an area where the chamfered portion and the tooth face meet are each composed of a curved surface in overall length.
First claim

The invention claimed is: 1. An intersecting-axes type gear mechanism comprising two gears configured to rotate in mesh with each other, respective axes of rotation of the two gears being disposed in an intersecting-axes manner, at least one of the two gears comprising teeth each of which comprise a tooth trace extending substantially in a radial direction and a radially inner end face, wherein a chamfered portion is formed on a meeting portion, the meeting portion being disposed where the radially inner end face and a tooth face of the each of the teeth meet, the chamfered portion extending over an overall length of the meeting portion, and at least an entirety of an area where the chamfered portion and the radially inner end face meet and an entirety of an area where the chamfered portion and the tooth face meet are each composed of a curved surface, and wherein the two gears constitute a hypoid gear comprising a ring gear, and the chamfered portion is formed on only a drive-side tooth face of the ring gear among the drive-side tooth face and a coast-side tooth face of the ring gear. 2. The intersecting-axes type gear mechanism according to claim 1 , wherein the chamfered portion is composed of a curved surface. 3. An intersecting-axes type gear mechanism comprising two gears configured to rotate in mesh with each other, respective axes of rotation of the two gears being disposed in an intersecting-axes manner, at least one of the two gears comprising teeth each of which comprise a tooth trace extending substantially in a radial direction and a radially inner end face, wherein a chamfered portion is formed on a meeting portion, the meeting portion being disposed where the radially inner end face and a tooth face of the each of the teeth meet, the chamfered portion extending over an overall length of the meeting portion, and at least an entirety of an area where the chamfered portion and the radially inner end face meet and an entirety of an area where the chamfered portion and the tooth face meet are each composed of a curved surface, and wherein each tooth has a tip surface that defines a ridgeline at an intersection with the tooth face, wherein the chamfered portion is composed of a curved surface, and wherein the two gears constitute a hypoid gear comprising a ring gear, and the chamfered portion is formed on only a drive-side tooth face of the ring gear among the drive-side tooth face and a coast-side tooth face of the ring gear. 4. The intersecting-axes type gear mechanism according to claim 3 , wherein each tooth has a tip surface that defines a ridgeline at an intersection with the inner end face. 5. An intersecting-axes type gear mechanism comprising two gears configured to rotate in mesh with each other, respective axes of rotation of the two gears being disposed in an intersecting-axes manner, at least one of the two gears comprising teeth each of which comprise a tooth trace extending substantially in a radial direction and a radially inner end face, wherein a chamfered portion is formed on a meeting portion, the meeting portion being disposed where the radially inner end face and a tooth face of the each of the teeth meet, the chamfered portion extending over an overall length of the meeting portion, and at least an entirety of an area where the chamfered portion and the radially inner end face meet and an entirety of an area where the chamfered portion and the tooth face meet are each composed of a curved surface, and wherein each tooth has a tip surface that defines a ridgeline at an intersection with the inner end face, wherein the two gears constitute a hypoid gear comprising a ring gear, and the chamfered portion is formed on only a drive-side tooth face of the ring gear among the drive-side tooth face and a coast-side tooth face of the ring gear.
